5 Preface In the last decade, we have seen tremendous successes in World Wide Web and Internet technologies. Traditional development techniques had to be adapted to this new situation, and at the same time new techniques emerged. Many research teams began to investigate different ways to adapt classic but still effective software engineering design and development techniques to the Web and Web engineering emerged as a new research field that relates several subject areas, including agents, e-commerce, e-learning, human-computer interaction, mobile technologies, security, quality and testing, the Semantic Web, etc. The International Conference on Web Engineering (ICWE) continued the tradition of earlier conferences with the aim of bringing together researchers and practitioners in these areas, trying to offer a good environment where people with different backgrounds could exchange their insights in this area. The success of this conference generated an incredible amount of work for the Program Committee members and the External Reviewers, lead by the Program Committee chairs Oscar Pastor López, Luis Olsina Santos and Martín González Rodríguez. We are immensely grateful for the effort they put into the process of selecting the very best papers. There were 190 papers submitted, with 25 papers accepted (13%) as long papers. A large number of papers describing ongoing research were included as short papers or posters. Unfortunately, we were forced to reject many good papers. Paper selection is always a difficult task. We want to thank all the members of the Object-Oriented Technologies Laboratory of the University of Oviedo (http://www.ootlab.uniovi.es) for their daily support and encouragement for this enterprise. The School of Computer Science Engineering of Oviedo gave its full support to the conference and we want to take this opportunity to congratulate it on its 20th anniversary celebration. In fact, this conference was part of that celebration. We also want to acknowledge the Department of Software Engineering research group at the Pontifical University of Salamanca, Madrid Campus, for its support in the organization and other practical matters. Thanks also to the Department of Computer Science of the University of Oviedo. We are also very grateful to Steven Furnell and Dieter Fensel for agreeing to deliver keynote lectures at the conference. May 2003 Juan Manuel Cueva L. B. Martín González R. Luis Joyanes A.
